Right. I'm okay with Berserk. But it has to have some kind of curse or magic behind it. Possibly the ward you mentioned. Lycans just can't do that. Doesn't matter how enraged you get. Also, make sure you're specifying that it's the magic that adds the weaknesses and strengths please. It's probably best if a Druid imposed that kind of magic. They tend to deal in nature and specialise in helping and or cursing Lycans. 

Give me some kind of story on that in your backstory and you're approved. I like him though. You got the speeds and strength just about where I imagined it to be.
